block redundancy check — (BRC) Information added to a transmitted block to verify accuracy of data before it is accepted. Block check data is developed by the sender as a predefined function of information in the block; the receiver performs the same function on… … IT glossary of terms, acronyms and abbreviations

Block check character — In telecommunications, a block check character (BCC) is a character added to a transmission block to facilitate error detection.In Longitudinal redundancy checking and cyclic redundancy checking, block check characters are computed for, and added … Wikipedia
Cyclic redundancy check — A cyclic redundancy check (CRC) is an error detecting code designed to detect accidental changes to raw computer data, and is commonly used in digital networks and storage devices such as hard disk drives. Blocks of data entering these systems… … Wikipedia
Longitudinal redundancy check — In telecommunication, a longitudinal redundancy check (LRC) or horizontal redundancy check is a form of redundancy check that is applied independently to each of a parallel group of bit streams. The data must be divided into transmission blocks,… … Wikipedia
Low-density parity-check code — In information theory, a low density parity check code (LDPC code) is an error correcting code, a method of transmitting a message over a noisy transmission channel. [David J.C. MacKay (2003) Information theory, inference and learning algorithms … Wikipedia
